SLIDING WINDOW.

Specification of Letters Patent.

Patented June 23, 1911.

Application filed November 23, 1908. Serial No. 464,037.

To all whom it may concern:

Be it known that I, name HALAsz, a subject of the King of Hungary, andresiding at Podmaniczkyutoa, 77, Budapest, Austria- Hungary, haveinvented certain new and useful Improvements in Drop-Vindows, of whichthe following is a specification.

This invention relates to windows the sashes of which are adapted to belowered to open and to be raised to close and further when in the raisedposition are pressed forward on to the packing strip mounted upon thewindow case, correspondingly with the outer surfaces of the sliding sashby means of a spring pressed pressing frame, the sash beingautomatically kept clear from the packing strip, when itis being movedup and down, by means of a U-shape metal plate mounted upon the sash andadapted to slide upon a flanged metal plate carried upon the springpressed pressing frame. In these windows as hitherto arranged in orderto fit the metal parts the window case requires double fluting whichconsiderably weakens the same and enlarges the basis of theconstruction; also the simplest form of metal plate provided upon thesash is in the shape of a U, having one limb elongated. These metalplates when made of iron are liable to rust and so cause the window tojam, and if made of brass or other nonoxidizing material are veryexpensive.

The object of this invention is to overcome these disadvantages byproviding upon each side of the sash a single flanged metal plateadapted to co-act with a groove or a similar single flanged metal plateformed in or upon the spring pressed pressing frame.

The accompanying drawings illustrate several modes of carrying out theinvention, Figures 1, 2 and 3 showing several forms of window insectional plan while Fig. 4 is a sectional elevation correspondingthereto and showing the sash in the closed position.

In the forms illustrated in the drawings, 3 represents the window sashwhich when being moved up and down slides in grooves formed in thewindow case, 11. When the window sash, 3, is in its closed position itis raised to its full extent and moved forwardly so that its lower edgerests in front of a slight rail or bar, 10, as shown in Fig. 4, it beingnecessary to slightly raise the sash and move it backwardly in order tolower it down the grooves in the side frame, 11, as usual in dropwindows.

A packing strip, 7, of velvet or other soft material is provided uponthe corresponding surfaces of the window case.

A frame, 1, Fig. 4, presses the sash, 3, under the action of springs,12, against the packing strip, 7, when the window is in the closedposition, this pressing frame, 1, being of any usual construction andhinged as usual at the top as indicated for example at 13, Fig. 4. A

Now in order to prevent the pressing frame, 1, pressing the sash, 3,against the packing strip, 7, when the sash is being raised or lowered,the sash, 3, in one form as shown in Fig. 1, is provided with a metalplate, 4, on each side edge, the plate, 4, having a flange, 5. Thelatter is adapted to slide in the guiding channel, 2, formed by thegroove in the pressing frame, 1, andthe plate secured to the outersurface of the side ledge of the pressing frame. The flange, 5, may rubagainst a metal strip, 6, secured to the frame, 1. Thus when the sash,3, is to be lowered, it is slightly raised from the position shown inFig. 4, and drawn backwardly so that it can fall down its grooves in theside frames. \Vhen the sash is drawn back its lower rail pushes back thelower part, 1*, of the resilient pressing frame, 1, and swings thelatter slightly about its hinges, 13. The sash then passes down behindthe rail, 10, and holds the rail, 1*, of the frame, '1, back and as theflange, 5, on each side during the falling of the sash runs in thecorresponding groove, 2, the plate, 6, holds the sash, 3, away from thepacking strip, 7, so that the sash can fall freely without any frictionor rubbing action occurring upon the packing strip.

The same action occurs in the form of the invention illustrated in Fig.2 wherein the plate, 6, of the previously described form is dispensedwith and a groove, 14, is directly formed in the pressing frame, 1. Thegroove, 14, however may be lined or strengthened if required by a plateof corresponding form.

Fig. 3 illustrates a third form of the invention in which an angleplate, 9, is secured to the side of the pressing frame, 1, with theangle or flange of which the flange, 5, on the plate, 4, secured to thesash, 3, engages.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a drop window of the type described,means for holding the sash clear of the packing while it is being raisedor lowered consisting of a single-angled flanged metal plate mountedupon the upper part of each side edge of the sliding sash so that themetal plate is substantially at right angles to the sash and the flangeis substantially parallel thereto, a spring-pressed pressing framehaving a groove in each side surface thereof-facing the side frame ofthe window the flange on each of the said plates being adapted to slidein the corresponding groove and co-act with the side nearer the sash ofsaid groove in the pressing frame, substantially as and for the purposeshereinbefore set forth.

2. In a drop window of the type described, means for holding the sashclear of the packing, while it is being raised or lowered consisting of,a single-angled flanged metal plate mounted upon the upper part of eachside edge of the sliding sash so that the metal plate is substantiallyat right angles to the sash and the flange is substantially parallelthereto, a

spring pressed pressing frame having an L shaped groove in each sideedge thereof and a metal plate for each of said grooves placed so as toform a U shaped channel, the flange on each of the singleangled flangedplates being adapted to slide in said U shaped channel and co-act withthe corresponding metal plate, substantially as and for the purposes setforth.

3. In a drop window of the type described, means for holding the sashclear of the packing while it is being raised or lowered, consisting of,a single-angled flanged metal plate upon the upper part of each sideedge of the sliding sash, a spring-pressed pressing frame, asingle-angled flanged metal plate on each side surface-facing the sideframe of the windowof said pressing frame, each of the former flangedmetal plates being adapted to slide on and co-act with each of thelatter substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
